Wrapping-Machines; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, whichform a part of this specification;

Heretofore many diilerent wrapping Ina-- chines have been devised some of which were designed to wrap candy caramels. These machines have not usually proved successful in use and the few that have actually been constructed and used, proved to be either'too slow in operation or wasteful of. the material to be Wrapped or the wrapping material, or unnecessarily complicated and likely to get out of order. The machines have usually Wrapped so imperfectly as to" retard their general introduction into use.

With this in view the object of the invention is to construct a wrapping machine adapted to automatically wrap the articles for which the machine is particularly adapted not only to enable the operation to-be performed at a-mu'ch higher rate of speed, but

as well to preventwa'ste of the material Wrapped or the wrapping material and 'to deliver the wrapped ar-ticles from the ma chine in absolutely uniform packages.

-A further object of the invention is. to

eliminate as far'as possible from the mechanism the possibility of breakage by providing release mechanisms for those parts sub to stress whereby abnormal pressure acts to disconnect or partly disconnect the endangered mechanisms from the driving element therefor.

his a further and important of the inventionto afford in connection with the wrapping machine, an improved: cutting mechanism whereby the articles to be wrapped (ingthis instance candy caramels,

although of course the; machine is adapted for any other, article), are delivered to the cutting mechanism in a continuous strip from which are automatically severed the candy cubes or caramels which are" then an:-

tomatically forced. into the carrying element of the wrappingmachinej together with a piece of waxed paper which is automatically caramel is brought into the machine, severed.

into cubes of suitable size and positioned for delivery into the carrying element.

It is a further and very important object of the invention to simplify the construction or wrapping machines in every particular and economize the power required for cutting the material to be Wrapped, for wrapping and delivering the same to the dis-- charge chute, and to so construct the machine as to enable the same to operate at a speed very much higher than has heretofore been possible for machines of this class.

It is a further and very important object of this invention to provide a machine of the class describedin which the driving and operating mechanisms are protected from dust and dirt, thereby preventing the mafrequently cleaning the machine.

The machine is manifestly adapted for Wrapping articles of almost any nature. The invention consists of the matters hereinafter describedand more fully pointed out and defined in the appended claims.

Fig. 35 is an enlarged sectional view showin the Geneva gear and the operation thereo Fig. 36 is an enlarged top plan view of the receiving chute and last end folding mechanism. Figs. 37, 38, 39, 40 and 41 are enlarged sectional details thereof. Figs. 42 and 43 are enlarged sectional views of the second end folder. Figs. 44 to 49. inclusive are enlarged detail views illustrating continuous operation of wrapping.

As shown in the drawings: Said machine embraces a suitable frame or table, a timing shaft, :1 wrapping wheel driven thereby, cuttin mechanism for the caramel or other articles to be wrapped, a paper cutter, a feed mechanism for the wrapping wheel, folding mechanisms and a discharge mechanism. Said frame as shown is constructed of metal, and comprises a table A, provided with an integral downwardly extending flange a on all sides thereof, at the bottom of which legs A are attached. A relatively large aperture is provided in the top of the table for the wrapping wheel and other mechanisms which project therethrough and at one end a recess orchamber is provided in the top of the table which extends transvers'ely the table for approximately the entire width and is Of a depth and width suitable to receive theftrain of driving gears whereby the various mechanisms are actuated. Journaled on said table is the timinging b shaft B which as shown is provided with a driving pulley b at one end thereof. Journaled on said shaft B is the wrapping wheel C which is provided on the side thereof opposite from the driving pulley b with an elongated hub or sleeve 0 through which said shaft B extends and which is journaled in a suitable bearing 1) thus affording a long bearing for said wrapping wheel on the timing shaft and in said bearing 6' as shown more clearly in Fig. 8. Near its opposite end said timing shaft is journaled in a bear- Said wrapping wheel as shown is provided with a plurality of oppositely disposed spokes as shown six (6) in number and indicated by c the ends of' which are connected with the rim c .Rectangular pockets are provided in the rim at each spoke to receive the articles to be wrapped. As shown leaf-springs 0*, are engaged on each side of each pocket and rigidly engaged in the bottom thereof in any suitable manner and converge slightly near-their outer ends and are provided with outwardly turned extremities as shown in Fig.- 13 to admit the article to be wrapped therebetween and firml engage the same, together with a piece 0 the wrapping paper. As shown, said outwardly turned ends of the spring blades 0 extend slightly beneath plates 0 engaged on the periphery of the wheel on each side of each pocket and laterally on each side of the wheel and which afford recesses to receive the free ends of said springs 0*. The spokes are axially cored as shown in Figs. 4, 5,6, and 11 to 14 inclusive and slidably seated in the bore is a sleeve 0, theupper end of which is of less internal diameter to aflz'ord a bearing for a spiral spring 0'. Through said sleeve and spring extends the stem-0",, of a plunger the head 0 of which is rectangular as shown in Fig. 11, and aifords a self adjusting bottom for the pocket. Secured on the inner end of said stem 0 is a stop engaged thereon by a pin 0 the inner end of which is of suflicient v diameter to extend into the end of said sleeve affording a stop for the other end of said spring. The lower end of said stop is enlarged in size to aiford a head and is provided with a rib 0" which engages in a radial slot in the spoke to prevent the plunger turning. A springbrake is provided for said sleeve. As shown a boss o is provided on the spoke near the pocket and 2 seated in a bore in said boss is a spring 0 one end of which bears against a key 0 which presses against'said sleeve 0 and the other end of which is engaged by a set screw 0 threaded into the outer end of the bore '12: and whereby any desired pressure sufficient to hold the sleeve in'any adjusted position may be secured. Saidwrapping wheel is shaped on its side adjacent the driving end of the shaft, B to permit the ends of said 13
